This invention relates to improvements cigar wrapping machines, and hasreference particularly to mechanisms for applying a wrapper and windingit around a cigar-bunch. v

The present invention has reference particularly to a mechanism of thekind referred to comprising a cigar-heading block and has for its mainobject to provide a cigar-heading block having a wrapper supportingmember and means for swinging said member so as to open said block,substantially with the view of permitting the wound cigar to betransferredfrom the wrapping mechanism in a simple manner and withoutbeing injured. Thus the heading block member does not interfere with thecigar on being transferred though said block is ordinarily mounted closeto the bunch head to convey the rear or flag end of the wrapper to saidhead. 7

In the drawing Fig. 1 is a plan view of a device constructed inaccordance with the invention; Fig. 2 is a longitudinal elevation of thedevice partly in section; and Fig. 3 is a cross section of the devicetaken on line 3-3 of Fig. 1.

Referring to the drawing two pairs of wrapping rolls l and 2respectively are mounted in known manner on arms 3 pivoted to shafts 4in the frame H3. A bell crank lever 5, one arm of which is pivoted totwo iinks ii, is pivotally mounted on a rigid shaft 15 in the frame it.The other ends of the links 6 each pivoted to the arms The free end ofthe lever carries a roller 8 which is forced against a cam 9 by atension spring I attached to the frame it at it and to the lever 5 at5'5. The cam 9 is secured to a continuously rotating driving shaft H.

Adjacent one end of the wrapping rolls 1 and 2 is mounted acigar-heading block it having a recess of substantially the same shapeas the cigar head. The top end of one of the arms 3 constitutes a memberi2 having such a shape as to form an upwards projecting wrappersupporting part of the heading block [3 when occupying a positionindicated with dash and dot lines in Fig. 3 The block member is locatedat the wrapper supply side and immediately below the front edge of atension plate 18 when the latter occupies its foremost position ondelivering the rear wrapper end to the bunch head. .The operation of thetension plate 18 as well as its driving means are well known in the artand therefore a deing pincher shaped gripper 2i hinged to a pin 22 onsaid arm so as to depend vertically and impart a parallel movement tothe cigar. The means for imparting rocking movements to the shaft 20 arewell known in'the art, and therefore nodescription thereof isneededherein.

In operating the mechanism a wrapper is supplied to a bunch M in theclosed cluster consti tuted by the rolls I and 2 in well known mannerfor instance by a leaf carrier over the tension plate is. The rear orflag end of the wrapper which is usually pasted is dragged by therotating bunch over the block member l2 and is completely wound on thebunch head. After finishing the rolling operation the cluster is openedby the cam 9 actuating the'lever 5 and the links 6 so as to swing thearms 3 with the rolls I and 2 apart to the position indicated with fulllines in Fig. 3. Then the wrapped cigar rests in the heading block I3and another rear supporting member (not shown). By swinging the left arm3 (Fig. 3) aside, the block member 12 is likewise moved aside, and thusthe heading block is opened to allow the cigar to be moved forwardly ina path of travel indicated by dash and dot lines in Fig. 2. Thismovement is obtained after having swung the arm 19 and the gripper 2i toseize the cigar by imparting to said arm a swinging movement in areversed right hand direction according to Fig. 2.

I claim:-

1. In a cigar-wrapping machine the combination with a rolling mechanismof a cigar-heading block having a member for supporting an overlyingwrapper when said Wrapper is supplied to the bunch, and means foropening the heading block by swinging said wrapper supporting memberaway from the other member of the block.

2. In a cigar machine having rolling mechanism and a tension plate, thecombination of a cigar-heading block having a member for supporting anoverlying wrapper and being arranged adjacent said tension plate, andmeans for opening said heading block by swinging said wrapper supportingmember, in a ih'rection forwards said tension plate.

3. In a cigar-wrapping machine the combina' tion with a rollingmechanism of a cigar-heading block having a member for supporting anoverlying wrapper when said wrapper is supplied to the bunch, aplurality of wrapping rolls, and

means for opening said rolling mechanism by swinging the rolls and thewrapper supporting member aside simultaneously.

6. In a cigar-wrapping machine the combination with a rolling mechanismof a cigar-heading block having a member for supporting an overlyingwrapper when said wrapper is supplied to the bunch, a plurality ofwrapping rolls, and transversally movable members supporting saidwrapper supporting member together with part of said 10 wrapping rolls.
